Summary
Material and methods: The influence of swim training on the function of the respiratory system was studied in girls and boys aged 10–18 years in whom a total of 1625 spirometries were done. Measurements included vital capacity, airfl ow in airways during expiration and inspiration, and maximum voluntary ventilation. Interpretation of the results was based on comparative analysis of age- and height-matched groups of girl/boy swimmers and sedentary controls.
Results: The effect of swim training on spirometric parameters with regard to anthropometric characteristics was investigated with the neural networks method. FVCEX and FEV1 correlated with height, arm span, and dimensions of the thorax. While airfl ow in airways during expiration was not affected by swimming, parameters defi ning inspiratory airfl ows were signifi cantly higher in swimmers who trained regularly for 7–8 years. This finding appears to be due to the effect of training on inspiratory muscles. MVV followed FVCEX values in girl/boy swimmers and controls.
Conclusion: The results demonstrate that vital capacity and airfl ow conditions in airways during expiration are not influenced by swim training.

K e y w o r d s: spirometry – swimming training – 10–18 year-old boys and girls.
